Question

The price of a gallon of gas in one month was
$2.60. The following month, the price was $2.99.
What was the percent increase of the price of gas?
A 1.5% x
B 13% ?
C 15% ?
D 39% x
I need some help with this question, I know that its obviously not A or D, but I don't know how to solve it to figure out if its B or C.

Answer 1

299/260 = 1.15
so multiplied 260 by (1 + 0.15)
which is 100% + 15 %
